Percy in Prisoner of Azkaban
In Prisioner of Azkaban, Percy has been promoted to Head Boy, as it is his seventh and last year at Hogwarts. He is still dating Penelope. We find another side to this complex character, a fun-loving side. During the last quidditch match of the season, Gryffindor vs. Slytherin, Percy bets Penny 10 galleons Gryffindor will win, and considering he doesn't have such money is quite excited when they do. (As is Oliver...) Percy is also able to show off his skills when it appears that Sirius Black has broken into the castle, and Percy (and all Prefects) are to watch over the other students in the Great Hall for the night.
